When MTV's 16 and Pregnant returns for Season 4 on March 27, we'll meet 12 new girls who are about to become teen mothers, with all the trials, heartache, and heavy decisions that come with having a baby at such a young age.

"I can’t model anymore, I can’t cage-fight," complains one of the girls, while a soon-to-be teen dad declares, "I still want to be a kid, you know, and have fun."

As we've learned from the stories of Leah MesserJenelle EvansKailyn Lowry, and Chelsea Houska on this past season of Teen Mom 2, being a young parent isn't exactly "fun."
